Ah, I was not aware of editorconfig-indent-size-vars.  I can update
the modes I maintain (ada-ts-mode, gpr-ts-mode) to use that instead.

Looking at editorconfig--default-indent-size-function, it looks like
if it also supported an "-ident" suffix, that would probably cover
ada-mode and gpr-mode as well.  Those modes are currently without a
maintainer, so might be good to either add them to
editorconfig-indentation-alist or to adjust the default function to
support the "-indent" suffix.
